Data sheet

The B&K Precision model 2640 is a battery operated, hand-held RFField Strength Meter capable of measuring RF levels and electric fieldstrength. The synthesizer-based design provides you with reliablemeasurements across a wide reception range of 100KHz to2000MHz, a remarkably low noise floor of -110 dBm to detect weak signals and basic spectrum analyzer functionality. The 2640 providesfield technicians and engineers with a cost-effective measurement toolfor basic signal investigations at only a fraction of the cost of a full-featured conventional spectrum analyzer.

The 2640’s user-friendly interface combined with convenient presetssuch as predefined filter settings and other special functions (e.g.squelch) commonly used in analog communication systems make the2640 easy to use. The B&K Precision 2640 supports RS 232C serialcommunication and includes software that can control the instrumentfrom a personal computer. The user can save the instrument’s measurement data on the PC for further analysis.The handheld RF Field Strength Analyzer is an ideal tool for field testing, installing and maintaining Mobile Telecommunications systems
